David,

I actually changed the column type from factor to character, and given the default as.is value, it now works smoothly. It is, nonetheless, still strange to my why it suddenly stopped working. Perhaps there was a version update or something similar.

Thank you David, Jim and Jorge for your help.
Cheers,

Balpo

Hello Jim

How can I ensure this reading it from the file?
The thing is, I cannot use the textConnection(), because the real file has millions of rows.

The advice being offered is not that you use textConnection. That is just for illustration. You would put a file="filename" argument in its place. Pay attention to the arguments for read.table().
